Lu Jianshuang entered the palace at the age of sixteen and started as the lowest-ranking maid in the clothes washing bureau. She had seen too many people climb up on the bones of others, so she learned how to do it. In the past ten years, the opponents she sent away turned into bones one by one, and she finally stepped onto the white jade steps and became the master of the middle palace. The night she climbed to the summit, she stroked her still young face in front of the bronze mirror, and suddenly remembered the first person who died in her hands - that person was only sixteen years old, and had two small tiger teeth when he smiled. Before he died, he asked her: "Sister, is the water cold?" From that moment on, Lu Jianshuang knew that she would never be able to clean herself in this life.
